Whaaaaat???? I won’t judge, you seem to be an audiophile.   That’s cool.  But what in the world did you just say?

Consider yourself sitting in a room facing an audio source. There are two paths from the speaker to your ears; one directly from the speaker to your ears, the other from the speaker, then off the walls, then to your ears. The latter is called room reflections. And these reflections reach your ear slightly later than the direct path. Due to phase cancellation, a comb filtering effect happens, similar to what's heard with audio phaser effects. Bass and lower mid-range frequencies can build up in what's called room modes. This is because the are natural resonances in any room. Basically, a room can become a speaker as it moves with the audio being played in it.
